Another object of the invention is to provide blocks of this characterof a novel construction so that they may be removably secured togetherin such a way that the blocks will be securely held, against accidentaldisplacement.

A still further object of the invention is the provision of blockshaving dovetail grooves,

and blocks having dovetail extensions to be fitted in the grooves sothat one block may he slid into position and the remaining blocks slidinto position thereabove, in the construc- 2 tion of a wall.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts, and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing: Figure 1 is a perspective view of one form ofbuilding block. Figure, 2 is a perspective view of a-modified form of"building block.

Figure 13 is a perspective View illustrating a narrow block having atongue extending from one end thereof, portions of the blocli adjacentto the tongue being beveled.

Figure 14 is a perspective view of'a block having a dovetail extensionformed at one 7 end thereof.

Figure 15 is a view of a block having a dovetail formed throughout thelength of one edge thereof.

Figure 16 is a perspective view illustrating a triangular buildingblock, the side edges thereof being formed into dovetails.

Figure 17 is a perspective view of a frame formed by assembling certainof the blocks.

Referring to the drawing in detail, the so invention embodies aplurality of building blocks of various types, the same beingprovidedwith groovesand extensions, whereby the blocks may be positionedone upon the other, or end to end, to hold them together.

The reference character 5 designates a building block having grooves 6disposed longitudinally thereofand arranged in adj acent side faces.These grooves are of dovetail construction, for purposes to behereinafter more fully described.

The reference character 7 designates a block of a similar construction,except that the grooves 8 and 9 thereof are formed in the side surfaces,at the opposite side of the block. The ends of these blocks are beveledas at 10, so that adjacent blocks when brought together in theconstruction of a corner, will provide a close fit. When sections 5 and7 are brought together, the aligning grooves receive blocks such asindicated by the reference character 11, the blocks havin dovetailedportions to be fitted in the dovetail grooves of the blocks. g

The blocks shown by Figures 2 and 3 of the drawing are formed withdovetail grooves 12 and 13 respectively, the block 14 having a dovetailextension to be fitted in a groove of the adjacent block, inconstructing a corner, the dovetail extension being indicated by thereference character 15.

As shown by Figure 4, the reference character l6 designates blocks thatare formed with beveled ends 17 and dovetailed grooves 18, the groovesbeing designed to receive the dovetail sections of the triangular block19 illustrated by Figure 16 of the drawing.

The block shown by Figure 6 of the drawing is formed with a longitudinaldovetail groove 20 to receive the dovetail extension of a block to beused therewith. The block indicated by the reference character 21 isconstructed primarily for use in connection with a block such as shownby the reference character 22, the block 21 being slid into the groove23 of the block, to secure two of such blocks together.

Dovetail tongues 24 extend from the ends of blocks 22 and 25, whichblocks are also formed with dovetail grooves 26. The reference character27 designates a block formed with a groove 28 along one edge thereof,and a dovetail tongue 29 at its end, the tongue 29 being designed to bepositioned in a groove of the block to be connected thereto.

A block 30 is formed with-a dovetail tongue 31 which is of a width tofit within a groove of a block to be connected therewith. The blockindicated by the reference character 32 has a dovetail extension 33 tobe slid into a correspondingly shaped groove of a block, the portions ofthe block adjacent to the extension being beveled as at 34.

The block indicated by the reference character 35 has a dovetail portion36 formed throughout one end thereof, while the block indicated by thereference character 37, has a dovetail portion 38 disposed along theedge, thereby providing similar blocks for various purposes.

In Figure 17, a frame is illustrated as formed by connecting the blocks39, which are shown more clearly by Figure 6 of the drawing, the blocks39 being connected by the blocks 27 that are shown in detail, by Figure10.

From the foregoing, it will be obvious that due to the constructionshown and described, building blocks may be arranged with respect toeach other, in the formation of various types of buildings, the groovesand tongues being of such constructionthat they will be interlocked tosecurely hold the blocks against accidental displacement.

I claim:

A corner construction for toy buildings comprising corner blocks havingdove tai grooves extending along and near the side edges and havingengaging mitered ends,

and a triangular block having dove tail exnature.
